How to reduce speed while moving left and right in 2D platform

Hello, I'm new in Unity, and I've just started making my own game - very simple 2D platformer, following a tutorial. I'd like to change the speed of my charakter while it is midair. Altrough I want to change the speed only while moving left and right. I don't want to change the speed of going up or falling down. Basically I'd like to reduce speed in x-axis only. I've already tried a few thing, but nothing has worked and probably it'd better, if I won't post it here. : )My script:

 public float runSpeed;
 public float jumpHeight;

 public Transform groudCheck;        
 public float groundCheckRadius;    
 public LayerMask whatIsGround;      
 private bool grounded;

 private Animator anim;


 // Use this for initialization
 void Start ()
 {
     anim = GetComponent<Animator>();
 }

 void FixedUpdate()
 {
     grounded = Physics2D.OverlapCircle(groudCheck.position, groundCheckRadius, whatIsGround);
 }
 
 // Update is called once per frame
 void Update ()
 {
     anim.SetBool("Grounded", grounded);

     if (Input.GetKeyDown(KeyCode.W) && grounded)
     {
         GetComponent<Rigidbody2D>().velocity = new Vector2(0, jumpHeight);
     }

     if (Input.GetKey(KeyCode.D))
     {
         GetComponent<Rigidbody2D>().velocity = new Vector2(runSpeed, GetComponent<Rigidbody2D>().velocity.y);
     }

     if (Input.GetKey(KeyCode.A))
     {
         GetComponent<Rigidbody2D>().velocity = new Vector2(-runSpeed, GetComponent<Rigidbody2D>().velocity.y);
     }

     anim.SetFloat("Speed", Mathf.Abs(GetComponent<Rigidbody2D>().velocity.x));
 }
